Sir Joe Quarterman & Free Soul

Rare groove is a DJ-driven crate‑digging culture centered on obscure, often out‑of‑print 1970s and early‑1980s soul, funk, jazz‑funk and disco records whose deep rhythms and rich arrangements worked beautifully on dancefloors. The term emerged in London to describe the rediscovery and club circulation of these hard‑to‑find sides, many of which later became staple break sources for hip‑hop producers and sample‑based genres. Although it names a scene and curatorial aesthetic more than a strict musical form, rare groove points to a recognizable sound: syncopated funk breaks, warm basslines, Rhodes and vibraphone textures, brass stabs, Latin and Afro‑Caribbean percussion, and emotive, often socially conscious vocals. Its emphasis on scarcity, collector culture, and historical recovery helped shape UK club taste and fed directly into acid jazz and other sample‑oriented movements.

Deep funk is a raw, hard-edged strain of funk that prioritizes drum-and-bass-driven grooves, terse horn stabs, and gritty, unpolished production. Emerging at the tail end of the 1960s, it captures the most stripped-down, rhythm-first aspects of funk—vamps on one or two chords, prominent syncopation, and an emphasis on “the one” —often recorded by regional bands on small labels and released as 7-inch singles. Vocals tend to be call-and-response or fervent shouts, while instruments such as drum kit, electric bass, rhythm guitar, Hammond organ or clavinet, and tight horn sections carry the energy. The term “deep funk” later became associated with crate-dug obscurities and a 1990s/2000s revivalist movement that honored the sound’s rugged, dancefloor-focused aesthetic.
